The SM-DP+ (Subscription Manager Data Preparation Plus) address is the eSIM server address used for manual eSIM profile download — an alternative to QR code scanning when activating Airtel eSIM on compatible devices. While most users activate Airtel eSIM via QR code or the Airtel Thanks app, certain scenarios require manual SM-DP+ address entry: QR code scanning unavailable, device-specific activation requirements, or technical troubleshooting when standard methods fail.
Understanding Airtel’s SM-DP+ address and manual activation process helps advanced users, IT administrators, and troubleshooters activate Airtel eSIM when conventional methods don’t work.
eSIM SM-DP+ Address: Setting up an Airtel eSIM can be confusing when your phone asks for an SM-DP+ Address, activation code, or QR code. The SM-DP+ address is an important part of the eSIM activation process because it tells your device where to securely download the Airtel eSIM profile.
Airtel eSIM activation is supported on many newer smartphones, including iPhone, Samsung Galaxy, Google Pixel, and other compatible devices. However, the exact activation method can depend on your phone model, operating system, and Airtel’s current activation process. In many cases, Airtel provides the required eSIM details through a QR code rather than asking customers to manually enter the SM-DP+ address.

Avoid using random SM-DP+ addresses found online because an incorrect address may prevent the eSIM profile from downloading.

eSIM SM-DP+ Address — History
The SM-DP+ (Subscription Manager Data Preparation+) system was developed as part of the global eSIM standard to replace the traditional physical SIM card with a remotely downloadable SIM profile. Its development is closely connected to the work of the GSMA, which created standards for remote SIM provisioning.
Early eSIM technology was introduced mainly for connected devices such as smartwatches, tablets, and industrial IoT equipment. Instead of inserting a physical SIM, a device could securely download a mobile operator’s subscriber profile over the internet.
As eSIM adoption expanded to smartphones, the SM-DP+ server became an important part of the activation process. It stores and prepares an operator’s encrypted eSIM profile and delivers it to a compatible device after the customer starts activation. The device may receive the SM-DP+ information through a QR code, activation code, or automatic carrier activation.
Apple, Samsung, Google, and other smartphone manufacturers gradually expanded eSIM support, while mobile operators began offering eSIM activation to more customers. Today, the SM-DP+ system operates largely behind the scenes, so most users do not need to know or manually enter the address.
For Airtel and other carriers in 2026, customers will normally receive eSIM activation information through the operator’s official activation process. The exact SM-DP+ address can vary by carrier and provisioning system, so users should not rely on unofficial addresses posted on random websites.
What is an SM-DP+ Address?
Technical Definition
SM-DP+ (Subscription Manager Data Preparation Plus):
The eSIM server infrastructure that stores and delivers eSIM profiles to devices. When you scan an Airtel eSIM QR code, your device connects to Airtel’s SM-DP+ server at a specific address to download the eSIM profile.
Components of eSIM activation:
- SM-DP+ Address: Server URL (e.g., smdp.airtel.in)
- Activation Code: Unique code linking your account to the eSIM profile
- Confirmation Code: Optional security layer (sometimes required)
When SM-DP+ Address is Needed
Scenario 1 — Manual entry devices:
Some devices don’t have a QR scanner for eSIM → require manual SM-DP+ address + activation code entry.
Scenario 2 — QR code scanning issues:
QR code blurry, expired, or screen display problems → manual entry alternative.
Scenario 3 — Remote activation:
IT administrator activating eSIM for employee device remotely → manual address entry.
Scenario 4 — Troubleshooting:
Standard QR scan failing → manual entry to diagnose server vs. QR issue.
